How a pen writes

PEN has a important role in our life .if we have to sign or write an application etc. we use pen in our daily life but how does that pen work. what is the mechanism behind the pen. let us now

you can see the ballpoint. As the pen moves across the paper ,the ball turns and the gravity pulls the ink down from the reservoir and onto the ball where it is transferred onto the paper . A ballpiont pen works exactly the same. the tiny ball held in the socket and the back is exposed so it can pick up ink from the reservoir. This is how a pen works.
i hope now you know about how a pen works.
